Jazztel, ¿CDN de Steam?

Comprobando qué conexiones persistentes tengo actualmente en mi ordenador, me fijo en que el Steam se conecta a IPs estáticas de Jazztel:

¿Steam utiliza servidores de Jazztel como CDN? Pregunta estúpida ante lo expuesto arriba, pero quizá sólo sea para la web y no para la descarga de videojuegos u otros servicios de Steam.

Antes esas trazas no terminaban en Jazztel sino que terminaba en un servidor tal que así: cdn-87-248-205-254.mad.llnw.net

Que yo sepa Steam usa akamai, lo normal es que no haya más de 8 saltos en ningún operador.

Como te dicen, Steam utiliza Akamai, que tiene cachés dentro de la red de muchos operadores alrededor del mundo, uno de ellos Jazztel.

Yo diría que tanto para web como para descargas, y no te imaginas la diferencia de velocidad.
